Building SCFW for Colibri iMX8X and Torizon

Dear Community,

starting from the article “Build Custom i.MX 8/8X System Controller Firmware (SCFW)”, I am working to build SCFW for Colibri iMX8X to get control some of the SCU/SCFW features. The procedure goes smoothly up to the actual build step, where I am getting this error:

~/build-scfw/packages/imx-scfw-porting-kit-1.5.1/src/scfw_export_mx8qx_b0$ make clean;make SOC=MX8QX B=colibri DL=2 R=b0 U=0 V=0 qx
make: *** No rule to make target 'build_mx8qx_b0/drivers/pmic/fsl_pmic.o', needed by 'build_mx8qx_b0/scfw_tcm.elf'.  Stop.

In detail, that dependency seems due to this sub-Makefile below. Do you have idea of why it is broken?

~/build-scfw/packages/imx-scfw-porting-kit-1.5.1/src/scfw_export_mx8qx_b0$ grep -r fsl_pmic.o .
./platform/drivers/pmic/Makefile:OBJS += $(OUT)/drivers/pmic/fsl_pmic.o

According to release matrix and porting documentation, I am using

  • SCFW firmware: based on imx-scfw-porting-kit 1.5.1 (imx-scfw-porting-kit-1.5.1.tar.gz)
  • ARM GCC toolchain 8-2018-q4-major 12-20-2018 (gcc-arm-none-eabi-8-2018-q4-major-linux.tar.bz2)
  • Toradex i.MX-System-Controller-Firmware.git commit bad4eef87700c1834f8510bdf72bd18826b87cd7

Of course, I am ready and willing to run commands or checks you can think are useful to troubleshoot the issue. Thank you in advance for the help and the suggestions.

Best regards,

Greetings @ldvp,

There’s a bit of additional information for building SCFW releases older than the latest. As per the table here: Build U-Boot and Linux Kernel from Source Code | Toradex Developer Center

You need match the git commit of our “i.MX-System-Controller-Firmware” repository to the specific commit for a release. So for 5.1.0 of our BSP you want to checkout commit hash “1f184f1”. You’ll want to do this right after you git clone and before you copy.

Best Regards,
Jeremias
